frame composed lof inwardly inclined-upf.V rights 4 affixed to the ends of parallel horizontal base timbers 114, and secured to getherlat their frontaand rear upper ends by crossftimbers-lOl and 100 respectively. Longitudinal timbers 97 are horizontally secured oneach side .to the saiduprights, to support the bearings 102 of the cross-shaft 50. Across-plate llconnects the two front uprightsf-4,l and supports the bracketed bearing 132'for the frontend ofthe shaft 49. A

cross-plate 99connects the two rear uprightsy 4, and-an upright 73extends from it to the cross-beam `100 to support the rear end of the. shaft4`9 which passes through a bearingopeni-ng init.. AThe numeral `96 denotes a cross-bar extending between and connected to. the basebars .114, anda bar 38 extends obliquelyfupward from the middle `.of 9.6.

4the lower end of the upright' 73.

-Thepwer-shaft .49:has on, its front end l a bevel-pinion and .onl its rear .end av worm 48. The bevel-'pinion :55 intemneshes .with

the t'eetltof the bevel-gear-wheel v54, the lattex' being .seated onthevertical shaft .14. The shaft `14- is slidable within `said bevelgear `-5,4 but notrotatablemithin it, as said swheelrotates-with .said-shaftv by reason .of

the' key 123 in the hub122 of said wheel prof ]ecting into the ,groove 121 Hon said shaft. 'The gear-wheel- 54.is`supp,orted. by the bearjing 116 restingonthe bracket 115 connected to the cross-plate 131. The shaft 14 is caused to reciprocate' vertically by means of a walking-beam or medially pivoted lever 15. The latter is pivoted on the cross-shaft 50, and

Aits'forward end has slotted bir`.urcations 1-9l Y which ride .'slidingly over pins 'projecting laterally from the xed sleeve 81 keyed at 20 to the shaft 14. The rear end of-v the walking-beam 15 has a friction roller .57 adapted to be moved over the 1cam 44 when lthe latter is rotated with the cross-shaft y46 on which itis secured. The cross-shaft 46 has is vends rotatably mounted in Abearings 98 affixed to the uprights 4 at the rear, and

on said shaft are mounted the gear-wheel 47 I and the single-face cam-wheel 45. The gear. wheel 47 intermeshes with and is driven by the worm 48, while the cam-wheel 45 drives thefriction-roller 56 on the upper end .of the lever 36, the latter being medially pivot-- ed in a bifurcated'support 37 extendinglforwardly from the uprightlll, and having its llower end pivted to Le bar'slidab1ycpn-- suitable base, has'its central disk 130 con- A nected to its circumferential plate-ring 28 by means of they two-lim-bed pieces 82, Whosey ends are secured tosaid ring by bolts 107.

A depending frame-work 106 is secured to` the under sides of the pieces 82, and on the under side of said frame-work are depending studs v75, in number the same as the regular divisions of the mold-carriage and spaced equidistantly apart. '.'L`he inner side ot' the fioiit eiid 0I' the arm 58 is provided lwith an inwardly turned hook 124, adapted to engage one voi' the studs '(5, when thrust forward and then drawn back by the action of they cam-wheel 4o. A'tensioii spring 126 is connected between the forward end of the arm o8 and some iixed portion of the frame on the inner side of the arm, to assist in i'etractiiig said arm against the nearest stud 75.

'Each of the pieces 82 has'bolt-holes 118 adapted to register' with the bolt holes 11i in the' projecting arms 83 of the mold-seats 84. As shown in Fig. 4, by this means moldseats of various diameters may be substituted for each other, when it is desired to change one set of molds of a certain'diameter for another set of a greater or less dimension'. Each mold-seat has a circular flange in which is seated the mold 12. The tonnen-head 13 on' the lower end of the shaft 14 is adapted to tit within the mold 12, and, be spaced away from the molds inner periphery to a .distance equal to that-'0f the desiied'thicknes's of the tile to be formed therebetween. To keep the mold in position during the operation of moldingflie tile y';lierein, a mold-coi er 1 is'provided, which has a central opening large enough to allow the. it'oriiierfhead 13 to pass therethrough. The mold-cover is of greater diameter than the mold, 'andf'has a raised rim 133, the latter being useful to prevent escape of the tile material, when the mold is being tilled. rl`he mold-cover 1 is attached to the long arms 2,

I which extend backward and are pivoted in bearings 3 secured to the reai uprights 4. These arms iiiay be elevated to lift the moldcover 1 away from the iiiold when it is desii'ed to remove the mold with the formed tile therein, by the following means.

. The numeral 16 indicates parallel vertical rods whose upper ends are'pivotally connected to the forward end ot' the walking-` beam 15, and whose lower ends after passing through orifices in rthe backward extension of the mold-cover 1 are connected and secured together by a cross-plate 64, the latter having lthe greater part o't its width extend ing rearwardly' from said rods. Placed in'- tei'iiiediately between the'rods 16 and fixed to the saine cross-plate 64 is an upwardly.

over the hooked end 62 projecting pin 70, adapted toy pass through an oriice in the said extension of 1, when the rods 16 are elevated to their higher position. bearing lugs 86, in which arepivoted thev On the top of said extension are n. .v

pintles of the forward end of a plate 5, mean] whose rear end is a rectangular opening adapted to re'ceiv.x and be engaged -by the hooked end 62 of the clutch-bar 69 whose lower end 63 is bifurcated and pivotally'connected to the brace 38. The clutch-bar 69 has 'its'upper portion bent obliquely forward and then again bent vertically upward for a purpose to be described. Said clutch-bar also has a rod 40 projecting rearwardly and whose rear end. is threaded and passes through an orifice in an angle-plate 39 secured to said brace 88. A nut 42 is secured on the end 43 of the bar 40, to adjust the latters rearward play, while between a xed ring 126 on the said vbar 40 and the angleplate `39 'is placed a coiled compression spring 41, adapted to exercise a resilient pressure forward on the bar 69. On each of the rods 16 above the extension of 1 is secured a. ring 18 by set-screws,- and between each ring 18 and the top of said eX- tension a compression spring 17 is placed and adapted to exercise a downward resilient pressure upon said extension when the rods 16 are also pushed down by the lower# iing of the front end of the walking-beam 15.

When the forward end of said walking-beam v 15 is elevated it carries upward the rods 16, until the pin 70 passes through the orifice provided for it in said extension of 1, and the said pin then cont-acts with the under side of the plate 5 and'lifts the latter at the instant that the rising rear edge of the crossplate 64 has contacted with the oblique .edgev of the bar 69 and pushed -its hook'62 back trom the forward edge of the rectangular ripening in the plate 5.l The further ascent of the cross-plate 64 brings it into contact with the under side ofthe extension of 1. so that tliellatter is lifted a proper distance to uncover thel mold 12, so that the latter may be carried around with the mold-carriage 28, and another mold be brought` about to the filling position. When-the forward end of the walking-beam 15 is. lowered. the reverse action takes place. the rods 16 descend,

disengaging the pin 70, and the plate .5

drops so that its rectangular opening passes of the bar 69 and thus becomes again engaged f to hold down the cover 1 upon the tile -mold '12 until the latter is filled and the tile formed therein.

1n order to secure the mold-carriage against movement during the timev that a tile is being formed in the mold, We have provided the following improved engaging removable means.' At. certain equidistantly placed locations in the upper edgeof the lesion .of the cover v1.

7`1=between the lugs .66 has its rear end ar ranged to slidev in-a ,slot 85 in the upright esac-1i plate-ring 28, .equal in number to the mold spaces :1n said carriage, are placed transverse notches =61 adapted to be engaged by aireciproeatory plunger 71. The plunger 71 is slidable through perforated lugs 66 on the front face of. an upright 68 secured to the cross-beam 96, and its upper end -is pivotally connected .to a downwardly projecting pin 67 attached to the lower side ofthe exten- -A cross-head .'74 connected to the plunger 68 to prevent displacement of said plunger, and a .compression spring .65 is placed 'beltween said cross-head and the upper .lug 66 to exercise a .resilient stress downward upon said plunger. When the-mold-cover 1 descends, the plunger 7l also 4drops its -lower end into o ne of the notches'. 61- and `secures the mold-carriage 28 in one position, until the operation of the machine causes the mold-cover to lift, when said plunger becomes. disengaged from the notchv long enough to permit` the mold-carriageto rotate Lto the extent of one of itssubdivisions.l

around the .tile-material, moves downward and then upward vagain through the extent of the. mold with a continuous spiral move- `ment, which forces lthe tile-material against the inner periphery of the mold and forms a tile when the tile is so-formed and the former-head in its upward. movement has cleared .the 'mold-cover 1 fora sufficient space, the' mold-,cover rises, and the plunger -71- becoming disengaged from the mold-carriage, the latter rotates through the space of one of its subdivisions; The mold with the formed tile therein may then be lifted of said carriage, and another' mold 4has in' said movement been brought into the proper position for filling with cement.

The part ofthe machine em loyed to fill the molds with the tile-materia is madeA and used as follows: Set in bearings 103 on the cross-beams 100 and 101, is a rotatable shaft 77 whose forward end projects over the car- 'riage 28 and is Supported by'a bracket` 52. A parallel shaft w25 1s rotatably mounted in the. bearings 108 on the same cross-beams, and has thereon a sprocket-wheel 22, a sprocket-chain 24 .passing over it and the sprocket-wheel 23 on the power-shaft 49. A

inigi 7G is mounted on the shaft 25 and intermeshes with a gear-wheel 21 on the shaft 77. By these means the shaft 77 is rotated,

c5. forward end. A shaft lll'is'journaled in with its sprocket-wheels 26 on itsV the ends .of the yoke 32 at the front -of the machine, and on this shaft are mounted .the sprocket-wheels 2 7, the upper part of said yoke being seated .on a rod 30, whose lower end is -threaded at '34; The lbifurcations-of said -yoke are connected by a cross-brace 112 through which 4the'threaded end of the -red 30 works, 'and :1n-adjusting nut being cured on' said rod below said brace wherebyl t-he :distance .of thel shafts 77A and 111 may be adjusted apart. The yoke members .am

also-braced 'to the barv112 by Iadjust-able members 387. Sprocket-chains 31 pass vabout the sprocket-wheels 26 and 27. A :single bucket 78 Yis suspended from .the sprocketchains 31, and the length 4of the 'chains is such that :they are vadapted to make o'ne -revf elution and `empty onebucketful of cement scooped ,from .the receptacle' .7 9 into the upper opening of the filling-cone .53 whenever a mold- 12 moves .into its filling position' on the mold-carriage-28.- 1

We have inserted in our improved ma.

chine, a friction-clutch'described as follows. On the power-shaft 49 a disk 87 is fixed near the bandfw'heel 8, the latter being slidable onsaid shaft. To the spokes of said band-wheel a ring 91 is secured by means of loops,92'passed about said spokes and having their ends clenched into the holes 93 in said ring. The ring 91A has a bearing 94on each' side for the levers 89, the rear ends-of said levers having ivoted thereto` the boxes.

90 having wooden riction blocks 88 adapted to-come in Contact with the circumferential edge of the-disk 87. To theother lends of the levers 89^are pivoted links 9, the latter pivoted to a collar 72 Yslidable on said shaft and having a forward concentrically grooved hub, and into said groove 10 are projected the inwardly 4bent ends` of the claws ,11 attached to the'le'ver 7. The said lever 7 is pivoted toone of the side-timbers 97. VThe lower end of the said lever is pivoted to aslide-bar 6 which is slidable within a loop attached to the forward upright, 4 on the Vopposite'side of the machine from the timber 97 to which the upper end of the lever 7 is pivoted. By means of this slide-bar, the lever 7 may be shifted so as to cause. the vslidable sleeve 7 2', to throw in or out-the forward ends of'thelevers 89 so as to either make thewooden friction-blocks 88 engage the edge of the disk 87 or to be' released therefrom. Thus the machine can be thrown in or out of operative relation to the power-wheel 8 as desired.
